i have a tv screen in my car and its not hooked up to anything. i was wondering if anyone knew of a program or something i could run through it that tells me my 1/4 mile time or horsepower or something usefull

 

Not through a tv screen. I know GTech sells a high end model that you can upload the information into a computer and look at graphs and stuff. There are other manufacturers that sell things like a GTech, but that is the only one I know of off hand.
